Spoiler Alert
This episode sees a flurry of activity, from awkward teenage moments to unexpected career twists and marital misunderstandings.
Study Buddies and Blushing Moments: Mao Tou takes the initiative to help Chen Xiu'e with her English studies. Hilariously, they're both equally challenged by the language, which makes them surprisingly effective study partners. Mao Tou even uses Chinese homophones to help Xiu'e memorize words, leading to some unexpected progress. Later, Xiu'e gives Mao Tou some folded clothes to put in Qian Jiayue's closet. Mao Tou, opening Jiayue's closet for the first time, gets flustered when he sees her neatly arranged bras and quickly makes his escape.
Ka Men's Diet Disaster: Ka Men is obsessed with her weight, meticulously tracking it and restricting her diet. Still feeling like she's not losing weight fast enough, she secretly buys some diet pills advertised in a magazine. The result? Constant trips to the bathroom with unstoppable diarrhea. During PE class, when she and Lu Yao are practicing their hosting lines, Ka Men has to make a mad dash for the toilet mid-sentence.
Diet Pill Intervention: Chen Mo and Qian Jiayue, worried about Ka Men, follow her and discover she's been taking diet pills. They immediately warn her to stop, explaining that these pills often just cause extreme diarrhea and are harmful to her health.
Gossip and Misinterpretations: Fangfang and her husband have a surprising encounter: they see Liu Songming and Li Qin leaving a residential building together, chatting and laughing. Fangfang, jumping to conclusions, secretly follows them. Her husband cautions her against gossiping, reminding her that it's a private matter and spreading false information could damage relationships. However, Fangfang can't resist sharing her "discovery" with Ai Ping and Chen Xiu'e. Xiu'e, with her big mouth, adds fuel to the fire, recalling how Li Qin used to cling to Liu Songming back at the factory. She wonders what's really going on and worries that Ka Men's mother might be losing control of the situation.
Ka Men's Mom Plays It Cool: When Ka Men's mother hears the gossip from her friends, she pretends to be unfazed, claiming she already knew about it. She explains that Liu Songming enjoys dancing, and Li Qin is just a dance partner. She also points out that Li Qin is married, suggesting there's nothing to worry about. Chen Xiu'e, concerned that Ka Men's mother is bottling up her feelings, offers support and even suggests confronting Li Qin, but Ka Men's mother doesn't take her up on the offer.
A Crushing Blow for Ka Men: Ka Men had planned to show Lu Yao a photo during rehearsal, revealing that they had hosted together years ago. But before she can, the department head arrives with some devastating news. The faculty has decided to replace Ka Men as Lu Yao's co-host, opting for Zhao Tingting instead. The reason? The height difference between Ka Men and Lu Yao is too noticeable, and the taller, slimmer Tingting would create a more visually appealing image.
Dreams Dashed, Then a Glimmer of Hope: Ka Men, who has worked tirelessly for the event, is heartbroken by the sudden change, especially since it's just before the European delegation arrives. Her teacher, Mr. Zhang, tries to argue against the decision, but the department head explains it was a unanimous decision by the faculty. Ka Men, not wanting to cause a scene, forces a smile and accepts the decision before running home in tears.
The Flight Attendant Audition: It's also the day the mothers are auditioning to be flight attendants. Qian Kang, Zhang Qiming, and Liu Songming plan to accompany their wives to the selection process. However, Ka Men's mother refuses to let Liu Songming accompany her. The other women give Liu Songming the cold shoulder. Liu Songming is confused about why his wife has been ignoring him lately, but he decides to stay at the shop since the audition is about to start.
Consolation and a New Opportunity: Ka Men sobs at home. Shortly after, her teacher, Mr. Zhang, arrives at the shop. He apologizes to Ka Men, feeling he didn't protect her interests. However, he has secured her a chance to be a tour guide for the foreign visitors, allowing her to practice her foreign language skills. Comforted by her teacher's words, Ka Men starts to smile again.
A Husband's Love and Support: Liu Songming, anxious to support his wife, rushes to the audition site by taxi. Ka Men's mother, seeing so many young and beautiful women, gets cold feet and loses her confidence, feeling her qipao might burst. Liu Songming arrives, sweating profusely, to encourage his wife. He reassures her that he reinforced the qipao many times, sewing it himself, and it won't have any problems. He also brings a brooch to adorn her qipao, revealing that he had been teaching Li Qin's husband to dance to earn extra money to buy it. This clears up the misunderstanding, showing Liu Songming's deep affection for his wife. Encouraged by her husband, Ka Men's mother regains her confidence and continues with the audition alongside her friends.
Participation is Key: Although the mothers are ultimately unsuccessful in the audition, they remain cheerful, emphasizing the importance of participation. The younger girls around them are inspired by their spirit, and Zhang Qiming takes photos of Ai Ping and the others to commemorate the occasion.
